【摘要】 1997年4～7月在莆田、福州、霞浦等地区抽查部分人群及家养畜禽粪便等，首次在猪、鸭、羊、鸡、鸽等5种动物中检出3种不同类型的O157大肠杆菌，其中O157：H7与O157：NM各8株,O157：N？5株，同时在1位腹泻患儿中分离到此菌。本文就这些O157分离菌株的生物学特性包括形态、生化、致病性以及药物敏感性等进行了实验，发现不同来源、不同类型的O157大肠杆菌都可致使小鼠发病死亡。在防治工作中应引起足够的重视。更多还原

【Abstract】 Three different types of E. coli O157 were first1y isolated from feces of five kinds in domestic ani-mals (pigs, chicks, doves. ducks and goats) and a diarrhoeal child in Putian, Fuzhou and Xiapu from April toJuly 1997. These E. coli O157 included 8 strains of O157: H7, 8 strains of O157:NM and 5 strains of O157:H?.The biological character (morphology, biochemical, pathogenic ability and drug sensitivity) of the strains weretesed and discussed.更多还原
